On running hands-on tests emphasizing usability under various conditions, the FZ35's control scheme is more traditional: physical dials permit aperture and shutter priority modes, shutter speed, and exposure compensation with little menu diving. It offers an electronic viewfinder with limited resolution and fixed LCD screen of 2.7 inches at 230k dots. The absence of touchscreen limits rapid menu navigation, and the lack of an articulated screen reduces framing flexibility.

The ZS70, however, benefits from a modernized user interface, including:

• A 3-inch articulated touchscreen LCD with 1,040k dot resolution, enabling high-precision previewing and touch focus control
• A higher resolution electronic viewfinder (EVF) at 1,166k dots with 100% coverage and 0.46x magnification, overall much more accurate for composition
• Improved menu responsiveness aided by the Venus Engine processor upgrade
• On-screen focus point selection with up to 49 focus points, enhancing precise subject tracking

These enhancements markedly improve the ZS70’s handling in dynamic shooting scenarios, such as street or wildlife photography, where rapid framing and AF adjustments are required.

Sensor and Image Quality: CCD Versus BSI-CMOS

Sensor technology fundamentally determines image quality and low-light performance. Both cameras utilize the common small 1/2.3” sensor size; however, the sensor types and resolutions differ markedly.

• The FZ35 is equipped with a 12-megapixel CCD sensor, a technology that, while standard at its launch, tends to exhibit lower high ISO performance and slower readout speeds compared to modern CMOS alternatives. The FZ35’s sensor size measures approximately 6.08mm x 4.56mm, yielding a sensor area of roughly 27.72 mm².

• Conversely, the ZS70 employs a 20-megapixel Backside-Illuminated CMOS (BSI-CMOS) sensor, slightly larger at 6.17mm x 4.55mm (28.07 mm² sensor area). The BSI architecture offers improved light-gathering efficiency, translating to superior performance in low light and greater dynamic range.

In practice, the higher pixel count of the ZS70 affords better resolution and cropping flexibility, though noise becomes more apparent at elevated ISOs. The ZS70’s maximum native ISO is 3200 (expandable to 6400 boosted ISO), a more realistic ceiling than the FZ35’s extended max ISO of 6400, which tends to produce unusable noise levels.

Testing under controlled studio conditions and practical scenarios demonstrates:

• The FZ35 delivers satisfactory image quality in bright conditions but suffers from limited dynamic range and noticeable noise at ISO 400 and above.
• The ZS70 yields cleaner images at higher ISOs, with improved shadow detail retention, benefiting landscape and night photographers.

Notably, both cameras support RAW capture, though the improved sensor and processor pipeline in the ZS70 allow higher-quality raw files that can withstand more aggressive post-processing.

Lens and Zoom Capabilities: Reach Versus Speed

Superzoom functionality is a primary attraction for both cameras.

• The FZ35 features a fixed 27-486mm equivalent zoom (18x optical zoom), with a constant aperture range of F2.8-4.4. This relatively bright aperture, especially at the wide end, provides better handheld shooting capabilities and shallower depth of field for portraits than many contemporaries.

• The ZS70, however, extends reach significantly with a 24-720mm equivalent (30x optical zoom), although the maximum aperture reduces to F3.3-6.4, meaning less light intake at longer focal lengths.

In practical imagery, the FZ35’s faster aperture translates into superior background separation potential and better low light telephoto shooting without pushing ISO. The ZS70’s extended zoom benefits wildlife and distant subjects but requires either higher ISO or tripod support in dimmer conditions due to narrower apertures.

The FZ35’s macro capabilities allow focusing as close as 1 cm, providing true close-up framing for macro enthusiasts, whereas the ZS70 requires about 3 cm, which can impose a slight limitation for detailed close-focus work.

Additionally, the ZS70 includes advanced focus bracketing and stacking, along with post-focus features, laying bare Panasonic’s attempt to cater to macro and focus-stacking aficionados with computational aids.

Autofocus and Burst Performance: Responsiveness Under Pressure

For wildlife, sports, and street photography, autofocus (AF) system functionality and continuous shooting rates often determine successful captures.

• The FZ35 employs contrast-detection AF with face detection capabilities but lacks continuous AF tracking (AF-C) and advanced multi-area AF modes. It supports only single AF and demonstrates a slow 2 fps burst rate, limiting its utility in fast-action scenarios.

• The ZS70 upgrades significantly with 49 focus points, contrast-detection AF enhanced by AI-based tracking, along with support for single, continuous, selective, and tracking AF modes. Touch AF on the screen provides manual override.

The impact on real-world shooting is tangible: The ZS70 locks focus quickly and tracks subjects smoothly in burst mode shooting at 10 fps, a fivefold increase over the FZ35. This characteristic favors sports photographers and wildlife shooters who require multiple frames per second to capture fleeting moments.

Video Recording: HD to 4K Evolution

Video features critically determine how these devices fare in hybrid photo-video workflows.
